Germany November 29, 1929 6 Claims. (01. 819) wool yarn move the skeinslocated on revolving bobbins through the washing liquid, whereby theyarn movement is caused by the friction between the yarn and the bobbin.It might happen, therefore, that individual layers of the skeins tangleup with one another. This will cause part of the filaments to beaffected by tensile stresses, whereas the others hang down in a sloppyway and might tangle up amongst each other so that the consecutivereeling becomes difficult and causes frequent breaking of the filaments.

The drive of these machinesis so designed that a shaft parallel to theyarn conveyor rotates the individual yarn bobbins by means of a wormear.

Sometimes the individual yarn bobbins are connected through spur gearsso that the driving of one bobbin will set in motion all the rest of thebobbins. Now, in order to give the rotating skeins an additionalmovement through the washing liquid, it has been suggested to installthe yarn bobbins on a frame movable in a parallel direction towards thewashing conveyor.

Those machines now in common use are operating satisfactorily with theexceptions of the above described troubles. They have, however, a verycomplicated drive which increases the cost of these machinesconsiderably. Furthermore, the drive is exposed to vapors detrimentaltoits metal parts which are located partly above the washing liquids.

There are, furthermore, known washing machines in which the skeins arelocated on stationary bobbins or sticks, while the washing liquid to theskein conveyor so that one of the most important requirements for auniform washing effeet is neglected, namely, a flow of the washingliquid in a lateral direction through the skeins. Also it is diflicultto remove the frames since the washing tanks are to be changed as soonas it becomes necessary to move the skeins from one bath into another.This is particularly important in the washing of artificial silk wherequite a number of difierent washing tubs are necessary. Thisinventionrelates now to a new machine representing a very simple drive especiallyadvantageous in the treatment of artificial silk. According to theinvention, the swinging levers operating the frame are equippeclwith adouble arm mechanism which runs laterally to the tub. The double armlevers are fastened on a beam parallel to the tub. Both ends of thesedouble arm levers carry the yarn frame on which the yarn is supported bymeans of sticks, bobbins, etc. The beam carrying the double arm leversis set into a swinging motion by means of a crank shaft drive. In thismanner the artificial silk is raised and lowered in the washing liquidand also moved to and fro parallel to the yarn conveyor. On account ofthe even load of each side of the double arm levers, this movement isaccomplished in an easy manner with a small power consumption. The yarnconveyor with its double arm levers rests in a loose manner on theswinging levers connected to the crank shaft and can be removed from onewashing tub to another, together with the frame, since the symmetricaldesign of the conveyor offers the advantage of an even distribution ofthe load.

The crank shaft drive for the swinging motion can be easily constructedin such a manner that it will not be located above the tubs andtherefore not be exposed to the detrimental influences of the liquidvapors. In addition to that, the lubricating oil eventually droppingfrom the driving mechanism will not ruin the washing liquid, Those partslocated above the washing liquid do not require lubrication.

The machine is well fit specifically for use with sensitive artificialsilk of fine filaments. yarn especially tends to be affected due tobeing tangled up as above described and can therefore be treated onlywith those machines in present use with difficulty, whereas, in my newmachine, only the velocity of the swinging motion has to be decreased bychanging the crank drive. A. decrease in the swinging motion will causethe line filament yarn to enter the washing liquid in a straightdirection, thereby eliminating the disadvantagesof the yarn being upsetat the moment of touching the surface of the washing liquid. .It isself-evident thatthe yarn can also be treated in the same manner in' theform of spools or cakes suspended on sticks which again arecarried onthe frame of the new machine.

This

ject of this invention, where:

Figure 1 shows the washing machine in a side elevation, partly in across section;

Figure 2 depicts the machine in a side elevation seen from thelongitudinal side, partly in a longitudinal cross section;

Figure 3 shows the same in a top view;

Figure 4 is a partial view of the carrier frame; and,

Figure 5' shows a cross section through the frame parallel to a carrierbeam.

The washing machine consists of two rectangular tubs "1, 1', which arelocated parallel to each other at such a distance that there is spaceenough between them for the two frames "3", 4. On the top end of theseframes "3", 4" is suspended, parallel to the longitudinal direction ofthe tubs, a beam 5, the bearing of which allows rotary movement. Thisbeam carries vertical to its longitudinal'direction, a double arm lever6", 7 on both ends. Two frames 10, "10 are fastened to theends of levers6", 7" by means of bolts 12", "13 and rods "8", 9. These rods areadapted to receive the skein conveyors "11.

The skein conveyors are shifted parallel to each other from one end ofthe frame into the slot 21", after the yarn has been placed upon thesticks. They are secured-at the other end by means of a key-way 22" onthe other side of the frame and held in position by means of a rod 24",movable around the hinge 25" so that rod "24 is secured by spring 23".

The beam 5 is suspended at one end on the frame 4" by the open bearing15", which carries the axle 14" about half of the round, whereas, theother end rests on a crank shaft "17, to which a crank arm 16 isfastened. The bearing of the double arm lever 6 carries an adaptersurface 26" in the form of a trapeze, permitting an immediate raising ofthedouble arm lever. Crank arm 16" is set in motion by a crank drive 19,"20. In the operation of the washing machine, the tubs 1, 1' are filledwith washing liquid. The crank drive 19, 20" sets the lever "16 intomotion which is transmitted over the beam" 5, double arm levers 6, '7and frames 10, 10" to' the skeins 27". Therefore; the skeins "27 locatedon frame "10 are lowered and raised continuously to and from the washingliquid.

After the washing process is completed, the skeins must be shifted toanother bath and the whole apparatus, consisting of beam 5 levers 6, 7"and frame 10, 10', must be raised liquid containing tanks,supports'located therebetween, one of said supports being provided withan open bearing, a lever pivotaiiy mounted on the other of said supportsand-having an enlarged and resting on said bearing and the rounded andof said lever, double armed levers secured to said beam, yarntransporting and carrying means secured to said levers and suspendedover said tanks,
